Disk prerequisite check fails when using an LVM image

[janegilring]

Describe the bug
OpenShift has the following prerequisite:
"Minimum 40 GB hard disk space for the file system containing /var/"

The prerequisite check for this fails when using an LVM image. When using a RAW image, it succeeds.

To Reproduce
Steps to reproduce the behavior:

1. Define the following OS in the parameters file:

    	"value": {
    		"publisher": "redhat",
    		"offer": "rhel-byos",
    		"sku": "rhel-lvm76",
    		"version": "latest"
    	}
   

2. See error after the OCP deployment script has run for a while.

Expected behavior
The deployment script should resize the /var when LVM is used.

Template Information (please complete the following information):

• OS: rhel-lvm76
• Branch: [master]

Additional context
As a workaround, we disabled the disk_availability check:
janegilring@393ac7d

The deployment did succeed, but we would rather not disable this check.

Hmm. At one point, LVM wasn't supported by OpenShift. That's why I used RAW and didn't include code to grow the volume for an LVM disk.

I see. As it is supported now, consider this a feature request :)
